BALL AND PROCESS FOR MAKING SAME.

Application led January 12, 1922. Serial No. 528,610.

T 0 all whom it 'may concern.' j

Be it known that I, HARRY N Yr., a citizen of the United States, and resident of Akron, in the county of Summit and State of Chio, have invented cert-ain new and useful Improvements in Balls and Processes for Making Same, of which the following 1s a full, clear, and exact description.

An object of my invention is the produc- 10 tion of a ball, particularly a base ball, that will be cheap and very durable, that will be affected in only a slight degree by heat, cold or moisture, and will stand hard usage.

Another object is the production of such a ball with a cover that cannot be torn loose from the ball by use.

Another object of my invention is a'process for the manufacture of such a ball that can be readily carried out with the minimum of special machinery and at a low cost. Other objects vof the invention will be apparent from the following detailed description and the appended'clalms.

In the drawings i Figure 1 is a diagrammatic view of the scrap from which the body of the ball is made.

Figure 2 is a partial sectional view of a narily composed of about equal parts of rubl ber and cotton fabric diagrammatically illustrated in Figure 1, the rubber being designatedv 1 and the cotton fabric 2. These trimmings or scraps are reduced to a pulplike mass in any suitable manner as by grinding and molstening. The exact manner in which this pulp-like mass is prepared is immaterial so far as my invention is concerned.

A conventional mold is shown in Figure 2 as comprising upper and lower plate members 3 and 4 with registering hemisphericalcavities 5 therein. The mold is filled with the pulp-like mass, and preferably somewhat more than filled as shown in Figure 3 where the material 6 is designated. The parts of the mold are pressed together and subjected to heat, which operation can readily be performed in a tire heater for example. This rst heating is carried far enough to cement the pulp-like mass together and effect a partial cure. The ball 7 then has the appearance shown in Figure 4, the joinin line being evident but the two parts being rmly held together.

As the next step, a cover is cut from pieces of tire material, and this iscut in two pieces of the usual base ball cover form as shown at 8 and 9 in Figure 5. The cover is placed on the ball which is then put back into a mold and subjected to a second heating which acts as a final and complete cure. This operation joins the cover to the body of the ball so rmly that it will not become detached and the finished ball 10 has the appearance shown in FigureA 6, the juncture lines 11 of the cover resembling seams.

The second mold should be slightly larger than the first mold because of the added thickness of the cover. The curing process is similar to that used in curing tires and can be carried out by lany one familiar with such operations. q

This ball can be made in the regulation base ball' size and will be nearly the regulation weight. It is very lively and will stand much more use than any base ball as at present manufactured.

I claim as my invention l; A process of making a ball which com-- prises preparing a pulp-like mass from the trimmings of tire stock, subjecting a quantity 0f said mass to a partial cure in a spherical mold to form a ball, applying a twopart cover of tire fabric to said ball, and subjecting it to a final cure in a mold, whereby the coverand body are rmly held together.

2. A process of making a ball which comprises preparing a pulp-like mass composed of substantially equal parts of rubber and cotton fabric, subjecting a quantity of said mass to a partial cure in a spherical mold to form a ball, applyin a two-part cover of tire fabric to said ba, and subjecting it to a linal cure in a mold, whereby the cover is intimately attached to said body.

3. A process of making a ball which com prises preparing a pulp-like mass composed of rubber and fabric, subjecting a quantity of said mass to a partial cure 1n a mold to form a ball, applying a two-part oover of a fabric containing rubber to the ball, and

subjecting it to a final cure in a mold to vu1` oanize the cover to the body of the ball.

4. A ball comprising a body composed of the trimmings of tire stock and a two-part cover cured thereto.

5. A ball comprising aI body composed of HARRY NYE.
